In the current digital age, security management has become an essential aspect of any organisation's operational framework. The rising number of cyberattacks and security breaches has put companies at risk of losing crucial assets, tarnishing their reputation, and incurring financial losses. For example, global cyberattacks increased by 38% in 2022 according to Security Magazine. Therefore, businesses must prioritise security management to safeguard their operations, employees, and customers. Security management comprises the formulation and implementation of policies, procedures, and protocols aimed at identifying, evaluating, and mitigating potential security threats. By effectively managing security risks, organisations can prevent data breaches, theft, and other malicious activities that could jeopardise their operations and negatively impact their stakeholders.
In this blog, we'll explore the pillars of security management and how each one is crucial to maintaining a secure and protected environment.
Pillars of Security Management
1. Risk Assessment
Risk assessment is a critical component of any security management strategy. It is a process that involves identifying, analysing, and evaluating potential threats and vulnerabilities to an organisation's assets, operations, and information. The purpose of a risk assessment is to provide a comprehensive understanding of the risks facing an organisation so that appropriate security measures can be implemented to mitigate them. The importance of risk assessment in security management cannot be overstated. Without a thorough understanding of the risks facing an organisation, it is impossible to implement effective security measures. Risk assessments help identify vulnerabilities in physical security line access controls and surveillance, as well as in cybersecurity like network security and data protection.
The process of risk assessment typically involves several steps. The first step is to identify the assets that need to be protected, like data, facilities, personnel, and equipment. Once the assets have been identified, the next step is to identify potential threats to those assets. This could include natural disasters, theft, cyberattacks, or terrorism. After the threats have been identified, the next step is to assess the vulnerabilities of the assets to determine how likely they are to be targeted by a threat and how easily they can be compromised. This involves evaluating the effectiveness of existing security measures and identifying areas where improvements can be made.
Once the vulnerabilities have been assessed, the next step is to analyse the potential risks and their potential impact on the organisation. This involves considering the likelihood of a threat occurring, the potential impact it could have on the organisation, and the cost of implementing security measures to mitigate the risk. After the risks have been analysed, the next step is to prioritise them based on their severity and potential impact on the organisation. This helps ensure that resources are allocated to the most critical risks first. Finally, a risk management plan should be developed to manage the identified risks by implementing appropriate security measures. The plan should outline specific steps that will be taken to mitigate each risk, assign responsibilities for implementing those steps, and establish a timeline for completion.
It is important to note that risk assessments should be conducted regularly to ensure that the organisation is aware of any changes to the threat landscape and to identify any new vulnerabilities that may have arisen. By conducting regular risk assessments, organisations can stay ahead of potential security threats and ensure that they have the proper measures in place to mitigate them (Source: Wikipedia).

2. Access Control
Access control is another crucial pillar of security management. It involves the process of restricting or allowing access to an organisation's assets, systems, and information based on a set of predefined policies and procedures. Access control ensures that only authorised personnel can access sensitive information, facilities, and equipment and that they can do so only within the parameters of their job roles and responsibilities. Access control is important in both physical and digital environments. In physical security, access control measures include security guards, locks, and access badges. In digital security, access control measures include passwords, encryption, and firewalls (Source: Sneha Segura).
The purpose of access control is to protect an organisation's assets and information from unauthorised access, theft, or damage. This is particularly important in industries that deal with sensitive information, such as healthcare, finance, and government agencies. The implementation of access control involves several steps. The first step is to identify the assets that need to be protected and the individuals or groups that require access to those assets. This could include employees, contractors, vendors, and visitors. The next step is to define access control policies and procedures that specify who is authorised to access each asset, under what circumstances, and for what purpose. These policies and procedures should be based on a least privilege model, which means that individuals are only given access to the minimum amount of information or assets necessary to perform their job duties.
After the policies and procedures have been established, the next step is to implement access control mechanisms. This could include the use of physical security measures like security guards and access badges or digital security measures such as passwords and encryption. Moreover, access control mechanisms should be regularly reviewed and audited to ensure that they are functioning effectively and that they are not being circumvented. This could include conducting periodic security assessments, reviewing access logs, and performing background checks on employees and contractors. Finally, it is important to ensure that employees and contractors are trained on access control policies and procedures and that they understand the importance of following these policies to protect the organisation's assets and information.

3. Incident Management
Incident management is the third crucial pillar of security management. It involves the process of detecting, responding to, and resolving security incidents in a timely and effective manner. Incidents can include anything from cyberattacks and data breaches to physical security breaches and natural disasters. The purpose of incident management is to minimise the impact of security incidents on an organisation's assets, operations, and reputation. It is critical to have a well-defined incident management plan in place to ensure that incidents are handled promptly and effectively, minimising the potential damage to the organisation (Source: AWS).
This process typically involves several stages. The first stage is detection, which involves identifying and analysing potential security incidents. This could be through the use of security software, monitoring systems, or reports from employees. The next stage is a response, which involves taking immediate action to contain the incident and prevent it from spreading. This could include shutting down affected systems, disconnecting from the network, or activating emergency response plans. Once the incident has been contained, the next stage is an investigation, which involves identifying the cause of the incident and assessing its impact. This could involve analysing logs, interviewing employees, or conducting a forensic investigation.
After that comes resolution, which involves restoring normal operations and ensuring that the incident does not happen again. This could involve patching systems, updating policies and procedures, or conducting employee training. The final stage of the incident management process is post-incident analysis, which involves reviewing the incident management process to identify areas for improvement. This could involve revising policies and procedures, updating employee training, or making changes to security software and systems. It is important to note that incident management is not just about responding to incidents when they happen. It is also about being proactive and taking steps to prevent incidents from occurring in the first place. This could include conducting regular security assessments, implementing security controls, and providing employee training.

4. Security Monitoring
Security monitoring is the fourth crucial pillar of security management. It involves the process of continuously monitoring an organisation's systems, networks, and assets to detect and prevent security incidents (Source: Science Direct). Security monitoring allows organisations to identify security threats and vulnerabilities before they can be exploited, helping to minimise the impact of security incidents on the organisation. The purpose of security monitoring is to provide real-time visibility into an organisation's security posture and enable proactive responses to potential security incidents. Security monitoring involves several activities, including network monitoring, system monitoring, and application monitoring.
Network monitoring involves monitoring network traffic to identify potential security threats like unauthorised access attempts, malware infections, and data exfiltration. This could be done through the use of intrusion detection systems, firewalls, and other security software. System monitoring involves monitoring system activity to identify potential security threats, such as unauthorised access attempts, system failures, and configuration changes. This could be done through the use of system logs, event management systems, and other security software. Similarly, application monitoring involves monitoring application activity to identify potential security threats, such as unauthorised access attempts, application failures, and code vulnerabilities. This could be done through the use of application logs, code analysis tools, and other security software.
Likewise, security monitoring also involves incident response, which is the process of responding to security incidents as they are detected. Incident response involves several activities, including containment, analysis, resolution, and post-incident analysis. Containment involves taking immediate action to prevent the incident from spreading and minimising the impact on the organisation. This could involve shutting down affected systems, disconnecting from the network, or activating emergency response plans. In security monitoring, "analysis" means identifying the cause of the incident and assessing its impact on the organisation. This could involve analysing logs, interviewing employees, or conducting a forensic investigation. Sometimes resolution is also sought at this stage.
5. Security Training and Awareness
Security training and awareness are the fifth crucial pillar of security management. It involves educating employees and stakeholders on how to identify and prevent security threats, as well as how to respond to security incidents. Its purpose is to ensure that all employees and stakeholders are aware of the organisation's security policies and procedures and understand the role they play in maintaining the organisation's security posture. Effective security training and awareness can help prevent security incidents caused by human error, such as phishing attacks and password misuse (Source: MimeCast).
Security training and awareness involve several activities. In this context, "employee training" means providing employees with the knowledge and skills necessary to identify and prevent security threats. This could include training on how to recognise phishing emails, how to create and manage strong passwords, and how to securely handle sensitive data. Security policy communication involves ensuring that all employees and stakeholders are aware of the organisation's security policies and procedures. This could include regular policy reviews and updates, as well as clear communication of security policies to all employees and stakeholders.
Security awareness campaigns involve raising awareness of security threats and best practices throughout the organisation. This could include regular security newsletters, posters, and other awareness materials, as well as training sessions and workshops. Effective security training and awareness programs also involve testing and assessment to ensure that employees and stakeholders retain the knowledge and skills necessary to maintain the organisation's security posture. This could involve conducting regular phishing tests or other security awareness assessments.

6. Physical Security
Physical security is an essential component of security management as it provides the first line of defence against potential intruders or attackers who may attempt to gain access to an organisation's premises, equipment, or personnel. Physical security measures can include both passive and active measures. While passive measures are designed to deter or delay potential threats, active measures are designed to respond to threats in real-time. Examples of passive physical security measures can include fences, barriers, or landscaping to limit access points or deter intruders from attempting to enter the premises. Additionally, passive measures may also include signage or lighting to alert personnel to potential hazards or risks (Specs: Tech Target).
Active physical security measures, on the other hand, are designed to respond to threats in real-time and include measures such as access control systems, video surveillance, and security patrols. Access control systems can include a variety of technologies, such as biometric readers, security gates, or smart cards, to authenticate and authorise access to restricted areas. Video surveillance can provide real-time monitoring and recording of potential security breaches, while security patrols can provide a physical presence to deter intruders or respond to incidents as they occur.
In today's digital age, physical security measures are also critical to protect against cyber threats that may target physical assets, such as data centres or industrial control systems. Cyber attackers may attempt to breach physical security measures to gain access to an organisation's digital assets or disrupt critical infrastructure. Therefore, organisations must consider physical security as a critical component of their overall security strategy to ensure the safety and security of their personnel, assets, and data.
